AUTOMATIC STOCK-SALTING DEVICE.

Application filed January 15, 1912.

To aZZ whom it may concern:

Be it known that T, JOHN I. IBLINGS, a citizen of the United States ofAmerica, and a resident of Cedar Falls, Blackhawk county, Iowa, haveinvented certain new and useful Improvements in Automatic Stock- SaltingDevices, of which the following is a specification.

My invention relates to improvements in automatic stock-salting devices,and the object of my improvement is to provide a saltreceptacle with ahinged cover which will automatically return to recover the opening insaid box, when said. cover has been displaced by any force and thenreleased.

Another object is to so contrive the forms and relations of the said boxand cover, that the cover will seal. the opening in the box when closedthereover to prevent the entry of rain or other extraneous material.

These objects I have accomplished by the means which are hereinafterdescribed and claimed, and which are illustrated in the accompanyingdrawings, in which:

Figure 1 is an end elevation of my said improved automatic stock-saltingdevice, with the cover raised, the dotted lines representing the coverin its lowered and covering position. Fig. 2 is a front elevation of theparts shown in Fig. 1.

Similar numerals of reference denote similar parts throughout theseveral views.

I am aware that different stock-salting devices have been heretoforepublished intended to effect an automatic readjustment of the coveringmeans when the said means have been first displaced and then released,but I have not found any such means operative, and thus have adopted theform here shown and described.

The box is formed of two hollow counterpart castings 1 and 2 whose edgesregister, and which are secured together by means of bolts 6 and nuts 5which fasten together their registering orificed lugs 3 and 4 projectingfrom their rear edges of junction. The part 1 of the box thus formed hasan integral lug on each end, projecting laterally in line with eachother, said lugs 7 having bolt-holes 16 for use in securing the box to aside-wall or other supportingmeans.

The general form of the box is that of a hollow cylinder with closedends, a part being left open at the upper frontpart and ends. A swingingcover 8 is formed as a Specification of Letters Patent.

segment of a cylindrical body, hollow, and of a little greater diameterthan the box body, in order to move freely thereover when being opened.It will be noticed that said cover has end pieces which overlap the endsof the box, outside of and parallel thereto, and that the angle of eachoverlapping end is pivoted to the end of the box adjacent to it, at apoint eccentric to the ac tual center point A of the box. The pivotpintle used for this purpose is a short bolt 12 secured in aseat-opening in the end of the box by means of a nut 17. It will also benoticed that the center of the arc forming the inner wall of the cover 8lies at the point marked B in Fig. 1., that is, forward of the pivot 12of said cover. The result is, that the distance from the pivot 12 to therear edge of the cover is less than the distance from said pivot to theforward edge thereof. This arrangement causes the rear edge of the cover8 when the cover is rocked back to its rear limit, to engage the outersurface of the box-part 1, preventing further backward movement. Forpurposes of adjustment, however, I have placed on the ends of thebox-part 1 a movable slide 13, mounted slidably by means of its slot 15on the outer end of a bolt 14 passed through the wall of the box andfixed in a desired position by a nut. This adjustment is usuallynecessary only to correct any misfit in the parts due to someirregularity in the castings, since the cover 8 is generally stopped atthe proper limit of movement by its engagement with the outer surface ofthe box.

The pivoting of the cover 8 at the point indicated, also has the effectof producing a large clearance of the cover when rocked backward. Thecover has a forwardly projecting lip 11, which when the cover is downprojects beyond the line of the box far enough to permit a beast to pushit to raise the cover. The cover being thus raised, there is suflicientroom between the cover and box to permit the animal to have access to adeposit of salt therein, and when satisfied, and the cover released, itinfallibly and automatically drops to its closed position as indicatedby the dotted lines in Fig. 1.

The forward upper edge of the opening in the box has a longitudinalflange 10 which serves not only as a stop in engaging a similar flange 9on the under rear part of the cover 8, but such flanges cooperate whenthe cover is in its lowered position to seal the joint at that place andprevent the seepage of rain or dust therethrough into the box. No rainor dust can work into the box from the other parts of the joints onaccount of their positions and overlapping at the junctions.

It is obvious that the cover 8 must always and automatically return toits closed or down posit-ion over the opening in said box, because itscenter of gravity is always located forward of its pivotal points 12.For that reason, whenever lifted and then released, it willautomatically return to its closed position, induced thereto by gravity,since the mass of the cover is so adjusted that its larger part isalways forward of said pivots.

If the cover were not so pivoted and formed relative to its pivots andsaid box, there would be no certainty that the cover could alwaysautomatically return to its closed position, and thus the contents ofthe box might become deteriorated or leached away.

Having described my invention, what I claim as new, and desire to secureby Letters Patent is:

An automatic stock-salting device, comprising a cylindrical trough withclosed ends and opening upwardly and to one side, an arcuate cover withintegral ends fitted over said trough and its ends and pivoted to thetrough-ends eccentrically to lift up from the trough in spaced relationwhen swung open thereover, the upper longitudinal edge of the troughhaving an outwardly-projecting rib, and the rear edge of said coverhaving an integral inwardly-directed rib, said ribs contacting when thecover is closed over the opening of the trough to seal the jointtherebetween, a slide-piece adjustably secured to one end of said troughand adapted to act as an adjustable stop for said cover, said troughbeing formed of two connected sections having fitting longitudinaledges, said sections having abutting longitudinal outwardly-directedflanges along their fitting joint, and means for detachably securingsaid flanges and sections together, one of said sections having anintegral bracket orifieed to permit of its being secured to somesupporting-body.

Signed at Waterloo, Iowa, this 26th day of Dec. 1911.
